Marlow has spent most of her life believing the shadowy demon she loves isn't real. Not only is he the living, breathing Prince of Hell, but he is now in serious danger. Their reunion is cut short as Caliban remains in a vicious battle with a Phoenician goddess after Marlow's escape. To save him, Marlow must venture into her ancestors' domain for help—the Norse Pantheon—where shared blood is no guarantee of an alliance and the line between gods and beasts blurs.

Marlow needs to believe she's crazy. The alternative would mean embracing the gift—or curse—shared by her mother and grandmother: she can see angels and demons, including a dark and haunting entity who's been with Marlow her entire life. At least, she believes that's all he is until a fae from the Nordic pantheon strolls into her life and informs her that she's been sharing a bed with the Prince of Hell.
